OIL-HEATER.

Specification of Letters Patent.

Patented Jan. 21, 1919.

To all whom it may concern:

Be it known that I, RUDOLPH HOFFMAN, a citizen of the United States,residing at Kankakee, in the county of Kankakee and State of Illinois,have invented certain new and useful Improvements in Oil Heaters, ofwhich the following is a specification.

This invention relates to heating stoves of the type known as oilheaters. Such a stove comprises a base, an oil tank, and a shell securedto the base'and surrounding the tank.

The object of this invention is to produce improved means for unitingthe base and the shell and for supporting the tank in central positionwith reference to the base and the shell.

In the accompanying drawings Figure 1 is a vertical sectional view of anoil heater embodying the features of my invention. Figs. 2 and 3 arefragmental horizontal sectional views. Fig. lis a perspective view of asecuring, centering and supporting member.

The annular base 1 comprises supporting legs 2. On the base is anannular upwardly extending flange 3 that fits within the cylindricalshell 4:. The base and the shell are secured together by means of asuitable number of members 5. These members may be formed of sheet metalas herein shown. In the construction herein illustrated, each memberconsists of two plates 6 integrally united by means of a web 7. At thelower portion of each plate 6 is a lug 8 that underlies the annularupwardly extending flange 3. Each plate 6 is recessed as at 9 toaccommodate the flange 3. Above the recess 9 each plate 6 is formed toprovide a tongue 10, there being shoulders 11 above and below saidtongue. These tongues are arranged to extend through slots 12 in theshell 4. and be bent into contact with the outer side of said shell, asshown in Figs. 2 and 3. Said tongues thus serve to secure the members 5to the shell 4, with the shoulders 11 in contact with the inner side ofthe shell. Preferably the upper surface of the lugs 8 is inclined sothat the base 1, the shell 4, and the members 5 shall be drawn tightlytogether when the tongues 10 are inserted through the slots 12 andclenched. The upper inner corner of each member 5 is preferably beveledor cut away as indicated at 13 to cooperate with the rounded lower edgeof the oil font 14 and thus guide the oil font into place. The font isprovided near its upper portion with an annular outwardly extendingflange 15 adapted to rest upon the upper edges of the plates 6.

It will be seen that the members 5 serve to secure the base 1 and theshell 4: together and also provide means for supporting the oil font andfor spacing the oil font away from the base and the shell so as toprovide an air space around the font.

I claim as my invention:

1. An oil heater having, in combination, an annular base having anannular upwardly extending flange, a cylindrical shell into the lowerend of which said flange extends, means for securing the base and theshell together comprising a plurality of members formed from sheetmetal, each member consisting of two vertical plates connected at oneedge by an integral web, a lug on the opposite edge of each plate at thelower end of the plate, said lug having an inclined upper surface toengage the lower side of the base, each plate being recessed toaccommodate said flange, each plate being formed above said recess torovide a tongue and a. shoulder, there being an opening for said tonguein the shell above said flange, said tongue extending through theopening in the shell and being clenched upon the outer side of the shellwith said shoulder in contact with the inner side of the shell, and anoil font adapted to fit between said members and provided with anoutwardly extending portion adapted to rest upon said members.

2. An oil heater having, in combination, an annular base, a cylindricalshell, means for securing the base and the shell together comprising aplurality of members each having a lug at the lower end thereof engagingthe base and a pair of tongues, the shell being apertured to receivesaid tongues so that they may be clenched upon the outer side of theshell,-and an oil font adapted to fit between said members and providedwith an outwardly extending ortion adapted to rest upon said members.

8. An oil heater having, in combination, an annular base, a cylindricalshell, means for securing the base and the shell together comprising aplurality of members formed from sheet metal, each member consisting oftwo vertical plates connected at one edge by an integral web, a lug onthe opposite edge of each plate at the lower end of the plate,

said lug engaging the base, each plate having a tongue and a shoulder,said shell being.

apertured to receive said tongue so that the tongues may be clenchedupon the outer side of the shell with said shoulder in contact with theinner side of the shell, and an oil metal, each member consisting oftwovertical. plates connected at one edge by an integral web, a lug onthe opposite edge of each plate at the lower'end of the plate,'said lughaving an inclined upper surface to engage the lower side of the base,each plate beingrecessed to accommodate said flange, each plate beingformed above said recess to provide a, tongue and a shoulder, said shellbeing apertured to receive said tongue so that the tongue may beclenched upon the outer side of the shell with said shoulder in contactwith the inner side of the shell.

In an oil heater, an annular base, a cylindrical shell, and means forsecuring the base and the shell together comprising a plurality ofmembers each having a lug at the lower end thereofengaging the base, a

pair of tongues and a shoulder, said shell being apertured to receivesaid tongues so that they may be clenched upon the outer side of theshell with said shoulder in contact with the inner side of the shell.

6. In an oil heater, an annular base having an annular upwardlyextending flange, a cylindrical shell into the lower: end of which saidflange extends, and means for securing the base and the shell togethercomprising a plurality of members each having a lug engaging the baseand'a part adapted to be secured to the shell above the base;

7. In an oil heater, a base, an annular shell rising from the base, andmeans for securing said parts together comprising a member having a partadapted to operatively engage with the base below the shell and a tongueadaptedto be securedflto the shell above the base, said tongue beingbent into engagement with theshell. ',8. In, an oilheater, a base, anannular shell supported upon the base, an oil font, and means forsupporting the oil font comprising a plurality of members each having atongue, said shell being apert-ured so that the tongue may be enteredtherethrough and bent into engagementtherewith, said font. having aportion adapted to rest upon said members.

In testimony whereof, I have hereunto set my hand.
